AZURA® Pump P 6.1L

Eluent delivery

For highly accurate and precise HPLC and UHPLC

The analytical pump AZURA P 6.1L combines all essential components of a first class HPLC pumping system. Three different configurations are available:
A 2×2 binary high pressure gradient (HPG) for high accuracy blending of up to two eluents from two selectable solvents each; a low pressure gradient (LPG) for reliable blending of up to four eluents and a very cost-effective isocratic version for easy analyses. Excellent separations with small particle size columns can be achieved with the high-performance pump heads featuring an extended back pressure.
Choose between pump heads with a maximum flow rate of 10 ml/min and 700 bar backpressure, or pump heads with a flow rate of 5 ml/min and 1000 bar backpressure. Special pump heads for Normal Phase applications will help to deliver robustly even demanding eluents like heptane or hexane. Pumps without a degasser offer a cost effective alternative.

High or low pressure gradient?

The choice of gradient formation technology is essential for a HPLC/UHPLC system. AZURA systems can be equipped with either a high or a low pressure gradient pump. Both techniques have advantages and disadvantages.

A low pressure gradient (LPG) module dynamically composes the eluent on the inlet-side or low pressure side of the pump head, by quickly switching between the different solvent channels. The AZURA pump technology adapts to the mixer volume and changes the valve switching cycle time accordingly.

The eluent in a binary high pressure gradient (HPG) system is composed by combining the solvent flows of two pump heads.

Choose a solvent mixer according to your application

The sophisticated micro fluidics of the AZURA Mixer combine high mixing performance with a low dead volume. The user-changeable mixer is available in different volumes (50/100/200 μl) allowing best possible adaption to any application or flow rate.

Isocratic analytical HPLC pump

The AZURA pump P 6.1L uses technology to overcome the challenges of pumping LC solvents at high pressure and high flow rates.The pump can deliver flow in the range of 0.001 – 10 ml/min at pressures up to 700 bar. 
The pressure sensor comes with an integrated and replaceable AZURA inline filter. The integrated AZURA inline filter is completing the analytical AZURA HPLC pump and turn this pump into a working horse in the lab. For biocompatible applications or ion chromatography this pump is also available with a complete metal free design. The pump features flexible 1/16“ capillaries, integrated compressibility compensation, integrated leak management and a constant pressure operation mode.
